Abstract
A chip card is described, preferably a contactless chip card, comprising a data-processing circuit for receiving, processing and/or transmitting data signals, and at least a capacitive switching element which can be activated by means of a user's touch, whose activation of the switching element triggers at least the transmission of data signals from the data-processing circuit and without whose activation at least the transmission of data signals from the data-processing circuit is prevented. This chip card is formed in such a way that an arrangement is obtained with little manufacturing effort, ensuring a reliable activation or deactivation of the chip card by the user.
